An initial structure-activity relationship study of the novel necroptosis inhibitor Nec-21 was described. Any changes of the tetracyclic scaffold were detrimental for the activity. Introduction of a substituent to 7 or 8 position (e.g., cyano or methoxy group, respectively), would increase the activity. The 7 and 8-position disubstituted compound 17b was 35-fold as potent as the lead, while EC50 reached 14 nM.

Gattermann reaction on substituted 1-hydroxycarbazoles (4a-d) afforded substituted 1-hydroxycarbazole-2-carbaldehydes (5a-d) from which synthesis of either 2-hydroxypyrido[2,3-a]carbazoles (7a-d) via Perkin reaction or 2- hydroxypyrimido[4,5-a]carbazoles (8a-d) via condensation with urea could be achieved.
